Thread: Can you find the answer to this "riddle" I thought of?

You're in a big building that's completely dark and boarded up. There are numerous pitch-darkrooms with tied up people in there, lined along the dimmed hall you're walking. You can only see the doors' silhouettes and nothing more. You're looking for a specific person. The question is: How can you find that specific person in the fastest way?

Call out their name and see if they answer?

Thumbs up to Melco, but wait how can you see the silhouette if the door if the room is pitch black?

I will see the answer of this riddle, which is the fastest way to find that specific person.
